Interface CubeRegion
- All Superinterfaces:
- Classifier, Element, ModelElement, MOFClass, Namespace, javax.jmi.reflect.RefBaseObject, javax.jmi.reflect.RefFeatured, javax.jmi.reflect.RefObject
- public interface CubeRegion
- extends MOFClass
CubeRegion models a sub-unit of a Cube of the same dimensionality as the
Cube itself, with each Dimension optionally subsetted in its list of members.
When
mapped to its physical source, a CubeRegion contains data cells identified
by the member combinations of the Cartesian product of the CubeRegion's
associated Dimensions and Measures.
The relative ordering of CubeDeployment
classes optionally implies a desired order of selection of the CubeDeployments,
based on implementation-specific considerations (e.g., optimized
access of aggregate data).
Synonyms: Sub-Cube, Partition, Slice,
Region, Area.
Misc. notes:
1. A CubeRegion is not a Cube, and
a Cube is not a CubeRegion.
2. A Cube has a Measure and CubeRegion
may have a corresponding measure (Measures are Attributes).
3. A Cube
may or may not have CubeRegions.
4. If a Cube does not have a CubeRegion,
then it's not physically mapped (it's virtual). All physical mapping is
based on the CubeRegion , not the Cube.

boolean |
isFullyRealized()
If true, then this CubeRegion has a direct physical realization and is not
bound by any MemberSelections. |
boolean |
isReadOnly()
If true, then the CubeRegion content is read-only (i.e., may not
be written or updated through the CubeRegion -- e.g., a CubeRegion
implemented via an SQL view may not permit updates to the underlying base
table). |

If true, then this CubeRegion has a direct physical realization and is not
bound by any MemberSelections. |

If true, then the CubeRegion content is read-only (i.e., may not
be written or updated through the CubeRegion -- e.g., a CubeRegion
